With the aim to investigate a possibility of supporting conservation of Lithuanian indigenous pigs (LIW) their external body and carcass measurements were compared with their wild boar (WB) hybrids to see whether crossing can improve the quality of pork, which in purebreds is inferior to other breeds. Depending on the proportion of WB in the crosses (1/4 or 1/2) purebred pigs were respectively 3.2 cm and 4.3 cm shorter at withers (P<0.05). Correspondingly, hind feet in 1/4 WB and 1/2 WB genotypes were 1.8 cm and 2.2 cm longer (P<0.05) whereas ear length was shorter by 1.9 cm and 3.0 cm (P<0.05) in the hybrid pigs. LIW pigs tended to have longer body and shorter snouts than hybrids (0.05

Celem badań była charakterystyka morfologiczna i rzeźna lokalnych świń litewskich (LIW) i ich krzyżówek z dzikiem (WB) z punktu widzenia wsparcia programu zachowania rasy. Ponieważ w czystości rasy świnie LIW ustępują walorami rzeźnymi innym rasom wykorzystanie dzika do krzyżowania zmierza do stworzenia lokalnego produktu. W zależności od udziału WB w krzyżówce (Ľ lub ˝) czystorasowe świnie były, odpowiednio, 3,2 i 4,3 cm niższe w kłębie. Stosownie, tylne kończyny u Ľ WB były dłuższe o 1,8 cm a u ˝ WB o 2,2 cm. Świnie LIW miały ogólnie dłuższe tusze o krótszych pyskach, w porównaniu do krzyżówek. Tusze krzyżówek były bardziej wypełnione, chociaż większy obwód stwierdzono tylko u ˝ WB. Krzyżowanie świń LIW z WB zwiększyło grubość tłuszczu na grzbiecie u ˝ WB. Wpływ płci na cechy rzeźne nie zaznaczył się na przestrzeni analizowanego wieku uboju. Główną korzyścią wynikającą z krzyżowania był wzrost powierzchni mięśnia najdłuższego grzbietu wraz ze wzrostem udziału WB w krzyżówce.
